Do you have an address or phone number for them. The only Fenwall Electronics I have been able to locate makes thermistors and related products.
Suppliers of SI thyristors will probably be Japanese, or be supplied by Japanese companies, like Powerex and Mitsubishi. To my knowledge, the SIT has...
100 Hz bandwidth at 28 kHz indicates a Q of 280. This is achievable, but is not enough of a specification to allow anyone to design a filter. You must know what the separation is between the passband and the stopband, what the minimum attenuation in the stopband must be, and how much ripple is...
I am trying to locate a source for static induction thyristors. I have had no luck trying to locate a domestic source, and the only Japanese source I have located (NGK Insulators) does not return my inquiries.
Does anybody have information on these devices, source information, factory reps, or...

and you will find Pspice V 9.1 Student version. It can be used to draw schematics and perform circuit simulations on small circuits.
Arrgh! I don't see a way to edit posts here. I wanted to add that the CO2, or other working fluid only gets cold where it expands. In princy's case, they allowed an entire cylinder of gas to expand. It got cold and froze. To avoid this problem, the liquid CO2 would be piped into an expansion...
AS princy noted, CO2 has a complicated phase diagram. At 68 degrees F, the material in a cylinder is a liquid with a vapor pressure of about 800 psi. As it vaporizes, it will cool rapidly and freeze. If you heat it, at about 85 degrees F it will come to a critical point, at about 1800 psi. Above...
